Hi all, I downgraded my Infinity using this method http://forum.xda-developers.com/showthread.php?t=1925230, then I unlocked my device using the Asus .apk unlocker. All was running fine until this morning when I rebooted my tablet, then all of a sudden it's stuck in bootloader. I finally got it out of bootloader, but now it can't find an update for JB. Can I just go to the Asus site, download the JB firmware and hopefully it should find it?? I really don't know what to do at this point.
Ok, I figured it out. I had to follow the Scrosler thread on how to update to JB and keep root. Delete thread if you'd like mods... thanks

Hello,
Well first off, I have unrooted the tablet already (I think). I followed this guide here:
http://forum.xda-developers.com/showthread.php?t=1154947&highlight=easy+unroot
I would have posted my question there, but apparently this forum wont let me post there since I do not have 10 posts yet.
I currently have version 3.2.1 installed, have the stock recovery installed, and do not have superuser showing in my apps list.
However, I am still not getting ICS OTA update. So I can only assume I've done something wrong.
I realize I can simply download ICS firmware update from asus and update it the same way I did 3.2.1 after unrooting, however that wont work. I'm trying to make sure OTA updates are working because I'm giving this table to my computer illiterate sister and need updates to work OTA for her.
Thank you for any assistance!
Asus pulled the OTA ICS update because of reported widespread problems with it.
Hello Steven6282,
any luck already? was ICS cancelled by asus?
Maybe the solution I mentioned in the post below will help?
http://forum.xda-developers.com/showpost.php?p=19468648&postcount=7
on that forum they have stock 3.2 Build of 8.6.5.13 in nvflash. But his depend if you are able to use nvflash (serial number of your tablet)? I used this method and then ota also works again. this way your tablet is really stock without tweaks.
goodluck.
Before anybody says to use the search function, I've been looking through the general topics non-stop for one that applies to my situation, and either it slipped through the cracks (likely) or it doesn't exist (not likely).
Basically, my tablet is rooted and unlocked, and I'm on ICS; the first one that had face unlock in it. I'd really like to update my tab to JB, but I need to be pointed toward directions for updating a rooted and unlocked tab. But on top of that, I also need recent instructions, because I know that earlier attempts at getting this thing updated have resulted in lots of bricked tabs.
If anybody could tell me if it's possible to update my tablet to JB right now, I'd appreciate it, and if someone has figured out how to do it, can you please point me toward that thread? I'd really appreciate it.

I'm in the same configuration, custom-ics-rom with twrp recovery on unlocked device.
I believe the first thing to do is enabling NVFLASH, that will make things safer also in the worst cases.
I did that and now hopefully I have an unbrickable device.
I'm a bit confused on how to go forward, I know that there are two versions of twrp, maybe I should install the JB version, booting inside it and then flash the downloaded JB update from ASUS site, or use the twrp for ICS for flashing and after that install the JB version ?
Anyone knows what is the correct option ?

Keep ICS, as JB will cause much trouble especially if you are rooted, trying to OC and is generally slowein my opinion
I prefer to try it anyway, tomorrow I will try flashing, after all if something will go wrong I should be able to recover with nvflash.

Thank you, Grim. That's disappointing to hear about JB, but if you think that my current build is better than that (which makes sense considering I've seen at least one thread about downgrading from JB to ICS), then I will keep my tab on ICS for now, and thank you for your input, I appreciate it.

If you have twrp recovery, can't you download the jb ROM from the Asus site for your region and flash it in? I'm unlocked and that's how I upgraded one version of jb to another, but my ICS to jb was ota, so in your case I can't speak from experience. There is a full upgrade, and root guide in the general section.

I just managed to do what you re looking to achieve.
I m pretty noob so it tok me a whole day to figure it out.
So first download jb update on asus website (pick the right one for ur type of tf300)
Flash it through adb
At that point i got jb installation working but bootloop
So i flashed jb version of twrp (adb)
I then went in recovery and flashed clean rom 2.5 which worked flawlessly
Just for the fun i did factory reset afetrwards and stock jb eventually launched right

I successfully installed jb following the guide on this site, the only thing that was not working was the flashing of the stock rom, neither given options worked (fastboot flash recovery or fastboot flash system) , I discovered that our eepad has a partition nmed staging used for firmware installs. I then flashed with
fastboot flash staging blolb
and all went good.
Btw I find the JB better than ics, more responsive and smoother, and also if it is not yet overcooked.
Hi,
I'm still on ICS bootloader on my TF300T, some unofficial CM based ROM and a new TWRP. How can I update my bootloader to support newest ROMs? Is it possible without ADB (ex. through terminal)? Does anyone have a ASUS ICS OFW, so it's possible to update OTA? Thanks in advance.

Theres a couple ways safest i've found is normal download and update. As far as ota if your unlocked no luck there but you can download from asus website place on root of sd or internal storage and wait for triangle to come up in notification back like as if ota. I would go through each update starting from where you left of before flashing cm especially going to 10.4.2.20 to 10.6.1.8 as it uses 10.4.2.20 as base for update from there. Remember once on jb bootloader your stuck there cant downgrade back to ics and theres some major changes to 10.6.1.8 and would have to reroot once get there but with the changes becarful as to what recoveries and roms u use once on 4.2.1 u can only use roms based on that and have to use the twrp 2.4.4.0 patched recovery but there are also alot of unknowns as to asus' new update so caution read and ask before flashing because many are bricking with no fix except nvflash right now. So also i would do and nvflash back up as if something should go wrong its your best and only way outnonce on 10.6.1.8 but back up before going through all this because as of now nvflash isnt available for jb 4.2.1. Goodluck and becarful.
Heresna good thread to read and ask questions on how to go about getting to 10.6.1.8 aka 4.2.1 most of all read and ask before getting into a pickle.

Yea of course good catch. THANKS. Also in some cases may need to rename as in some times when get to 10.4.2.20 or 10.6.1.8 may have to rename. US_epad-user-10.6.1.8.zip of course not alway US could be WW for world wide or etc but as your updating may not always be the case just i've heard of some having to do this. This also works for downgrading and renaming your current firmware version as a previous version to do a reinstall had to do that once to fix a random reboot problem and works. I've heard of some downgrading as far as first jb build but thats as far as i've seen anyone can go.
Good luck as far as getting back to stock not totally sure you may know better than me or can ask some one on the thread i gave you i've never been rooted because affraid to void warranty just to safe but been doing alot of reading a research for when i decide to do so. Rooted like 10 of my passed other phones why not this one eventually just being safe from what i've seen happen to people with this new update.

I'll second this advice. I just upgraded my tablet from ICS yesterday, too, and this is exactly what I did. It worked great. I stopped at the last 4.1 update, though, because CM won't work on 4.2 yet.
And I second^2 the advice about setting up NVFlash before flashing the Jellybean update. I did that, too. Of course, I was doubly motivated by the fact that I had just recovered from a seven-month soft-brick (which was why I was still on ICS).
Anyway, good luck, and enjoy the Jellybean update.

Thanks, I'll NVflash first... Just where do I get androidroot.mobi bootloader from? Can't find it.

The NVFlash thread links to a page at androidroot.mobi about the NVFlash release. That page links to a guide. At the bottom of the guide are two things you have to download (there are many links to downloads, but you only need the two that correspond to your OS and tablet). One is the NVFlash binary. You'll know because it only contains one file called NVFlash. The other includes the specific files for your tablet, including the bootloader.
So, just follow the guide on the AndroidRoot.mobi site, and you'll be fine.
Edit: Here's the guide I'm talking about: http://androidroot.mobi/t3_nvflash/
If you're using Windows, you may actually need to download three files, the third being the drivers.

In windows, the android SDK/Fasrboot are more clear to me, so I'll now just download the ROMs and files for later use. Thanks everyone
I just got my tablet today and im stuck on trying to get it upgraded and rooting it, Ive unlocked it but thats as far as I can seem to go. I cant update from my tablet as "No updates are found".
I did find this thread but it came up with file not found when I went to my firmwre
The Build Number is IM74K.WW_eepad-9.4.3.30-20120604, I looked on the website but couldnt seem to find an update for it.
If it's to root it (Im using Linux) so I can add a Custom ROM then please let me know im still relatively a noob when its comes to rooting etc using Terminal.
If you are still on ICS, you def want to read about nvflash backup. Once you upgrade, this safety net is gone forever !

Yes I have just helped someone with this same request.
You can have a look at my how-to upgrade/downgrade for any JB firmware
However as your coming from ICS have a look at my posts on the last page of this thread, page 243. There are detailed steps on how-to upgrade from ICS to JB 10.4.2.9 then to JB 10.4.2.20, you could also go from 10.4.2.9 to 10.6.1.15.3 here but just make sure you have the correct twrp version - see posts for details on which twrp version to flash for each bootloader
Once on a JB firmware you can follow my how-to to jump between any JB firmware.
Just make sure you flash the correct version of twrp for the bootloader your on.
Let me know if you need any help with any of the steps or have any questions
Im currently stuck on trying to flash TWRP to my device. Im using Linux so unsure of what the commands are for "flashing" it via the terminal. Ive got ADB set up and luckily found a script to root my device. I've got it up to JRO0C.WW_eepad-10.4.2.9-20120809 (Android 4.1.1) now but as I said getting the recovery installed is another game.
Hi all, I just picked up this TF300T and accidentally updated it to 10.6.27.5 and can't seem to find any root that works with this version, I was wondering any of you guys have any idea how to root it? i already have it unlocked with the official asus unlocking apk.
also just a side question, my TF300T seem to be running extremely slow and glitchy, any ideas? or is the stock rom just not that great?
Thanks.
Edit:
also side note, I was able to boot to recovery, but it doesn't have the USB icon in the middle
it's got RCK / Android / WIPE DATA
if i click RCK it just gets stock there with the Android guy open with a red ! on it
it i click Android it just boots into normal OS
and wipe data is prob just wipe data havn't tried this yet
Update:
I got my tablet rooted.
in here it'll help you downgrade to 10.6.8.1 and all that good stuff.
please visit for more info
http://forum.xda-developers.com/showthread.php?t=2195883
and also just FYI.
use [openrecovery-twrp-2.6.3.0-tf300t-JB] when i used the 2.5.0.0 my screen was split in half.
Sorry - seems like I just posted the exact same question.
I will just add that I tried to install CWM recovery before updating the FW to 10.6.1.27.5 and had the exact same problem with the previous FW.
does anyone know if i can downgrade it from 10.6.27.5 to 10.6.27.1 or even before that?
thanks.
just fyi

that's what i am trying to do as well.
I just trying to read forums but there is no talk about the new bootloader,
My tf300 feels so laggy compared to galaxy tab 2.
I love the size and storage of the tf300 just it lags and feels very slow.

Welcome to XDA,
To solve any problems with your device, 1st search and read, read, read! Then ask questions if you can't find it. If anyone helps you, thank them using the "Thanks" button. Take things slowly, don't overload yourself with information. Eventually you'll be a pro and helping others out.
Watch this to learn not how to be a n00b new user and to be a good user. :laugh:
https://www.youtube.com/watch?v=JmvCpR45LKA
If you read enough, you would of learnt all (stock) TF300T users lost root after the update to .27.1, and also .27.5.
To get root, try downgrading and rooting via mottochopper
Read these:
Mother of all guides and then some
Downgrade Android
Use this for root afterwards, works with versions before .27.1
Have fun rooting! If you have any questions, I'll be happy to answer them.
Hit that thanks button, its a good habit to get into.
